BHAT

The BHAT Bottom Hole Assembly Tool is a tool designed for easy MU and BO of the bottom hole assembly. It allows the operator to assemble and dis-assemble the bottom hole assembly in a safe way due to built-in safety features.

The tool has a triple safety built in to prevent dropping objects. First it detects if any pipe is
present in the tool. Second it measures if any pressure is set on onto the holding nuts and third
it measures if any pressure is applied to the slips.

A secondary retention system is provided to hold the pipe should the hydraulic power to
the tool be lost. A spindle and lock nut design with hydraulic drive motor will provide full
mechanical lock. The tool will continue to hold the pipe even with full loss of hydraulic power
(once the tool has provided a positive lock signal). If the answer to all these questions is
positive, only then the driller receives the signal "open elevator".

The tool has a “no slip” design and will grip all sizes within its range without insert/size change

The tool can be placed with an adapter plate on the master bushing and on top of the PS30.

With adapter plate the tool can be fitted directly into the 37.1/2” rotary table opening, lowering
the overall height of the tool.

The tool uses a dedicated hydraulic system via stand alone control panel OR by using the
drillers console.

The tool is low enough so that a standard iron roughneck can still be driven over the tool to
make up the DC connections.
